The map is in active development, and will/may get more features. keep up with changes here: https://forums.bohemia.net/forums/topic/227617-community-upgrade-project-cup-maps-20/

If we add stuff ourselves, it wont show on the in game map, so I want to avoid that.

Not a fan of this idea. Getting good loot should take time not multiple mil bases. Adding more loot you may as well spawn with a load out. IMO the loot table is too high as is.
